FLOOR AND CEILING.

SPECIFCATION forming part of Letters Patent N o. 684,1 16, dated October 8, 1901.

Application Jfiled January 22, 190].. Serial No.441311. (No model.)

To all whom it 11mg/ concern: t

Be it known that I, HANS SIEGWART, a citizen of the Republic of Switzerland, residing at Lucerne, Switzerland, have invented new and useful Improvements in Floors and Oeilings, (for which I have applied for apatent in Switzerland, dated June 28, 1900, application No. 24,284,) of which the following is a speciication.

The present invention has reference to improvements in floors and ceilings in buildings, and relates more especially to floors or ceilings used as heat or cold transmitters for heating or cooling rooms; and the object of the invention is to provide a floor or ceiling, respectively, which allows of a constant current of the heating or cooling medium passing in at one side, circulating freely through it, and passing out at the other side, as will hereinafter more fully be explained, reference being had to the drawings.

Figure 1 is a horizontal section through a floor or ceiling according to the present invention. Fig. 2 is a section on line A A of Fig. l. Fig. 3 is a horizontal section through a modiication. Fig. 4 is a section on lineB B of Fig. 3. Figs. 5, 7, and 9 are horizontal sections through as many modifications. Figs. 6, l8, and 10 are sections on lines C C, D D, and E E, respectively, of Figs. 5, 7, and 9.

Referring to Figs. l and 2, the beams a', a2, a3 to LX are provided with longitudinal channels b, running parallel to each other when the beams have been laid out alongside of each other. These beams consist, preferably, of concrete bound with iron sheeting. They are carried in the ordinary manner by the vertical walls d e of the room and carry in turn the flooring or covering c and serve at the same time as ceiling for the underlying room. The walls of these beams touching each other are provided with corresponding apertures or passages f, thereby placing the channels b into communication, as is clearly shown in the drawings. The adjoining walls of the last beam ax and the one next to this last beam are not perforated. In the wall c are provided vertical lues h t'. The one of these-for instance, his in connection with a source of heat or cold, (not shown in the drawings, as forming no part of the invention,) and the other iue 'L' is in connection with the chimney "Iluebpenings or also with the source of heat or cold for revheating or recooling the air or the other mei dium sentthrough the beam system. The longitudinal channels of the first beam er and of the last beam ctl` are open at the ends, resting in the Wall e, and communicate with the lues h and t, respectively. The channels b of the last beam and the one next to this last beam also communicate at the ends resting in the wall CZ. The cooling or heating mediumL being forced up the ue h enters the longitudinal channel of the rst beam c', Hows through the various channels and passages of the beam system, and finally enters the outilue @which preferably carries it back to the source of heat or cold, respectively, t0 be used over again.

Referring to Figs. 3 and 4, the beams y', y?, ya to 'yX are provided with longitudinal channels and passages m. The channels are divided by the partition-wall l into two halves b and b2. The beams are arranged parallel to the wall e', which is provided with an 'inlue h 'and an out-flue t'. The beam nearest to the wall 'e' is provided with two apertures, one in either half b' b2, corresponding to the The longitudinal channel of the last beam yX is not divided. The cooling or heating medium entering through theue h' passes first through the the beam-halves b',

through the last beam yx into and then` through the beam-halves b2, and out through the flue t.

Referring to Figs. 5 and b', the beams e,

c2, d3 to 2X are provided with channels n.

These channels are connected by passages provided in the sustaining-walls in such a way that the cooling or heating medium is forced to take a zigzag course through the channels, entering through flue h2 and escaping through flue The left half of Fig. 5 shows a construction where the channels are arranged in pairs, whereas the right half shows an arrangement of singlechannels.

With reference to Figs. 7 and 8 the beams fo are provided with channels n'. The wall e' contains the influe h3 and the outflue 3. The beams are all open at both ends and communicate at one end by means of a passage provided in the sustaining-wall'and communicate at the other end by means of two pas sages provided in the wall e2, so that two IOO groups of beams are formed. rlhe cooling or heating medium entering through the flue h3 iiows through the beams of the first group, passes over into and through the beams ot' the second group, and out through the flue t3, 'as is shown by the arrows in the drawings.

Referring to Figs. 9 and 10, the beams w are provided with longitudinal channels @b2 and are arranged parallel to the wall e3, containing two influes h4 and an outline 714. The iniues are arranged one at either side of the outflue. Below the beams w are arranged two cross-beams tu, with channels s communicating through passages t in the beams w with the channels m2. The channel s of the one cross-beam communicates with the outi'lue i* and the channel s of the other crossbeam with the right infine h". j The cooling or heating medium entering through flue 701 passes into and through the channels of the cross-beams w', into and through the channels 102, then into the middle cross-beam tu', and out through flue t". The ends of the beams w are closed by a U-shaped cap and rest wit-hin the wall r. The adjoining walls ot' the beams w are provided with corresponding passages u, which take the place of the channeled cross-beams w.

In a building provided with floors or ceilings of the described construction these Hoors or ceilings may all be supplied from a common source of heat or cold, or the floors or ceilings of each story may have a separate source of heat or cold.

Instead of using single-channeled beams the floor or ceiling may also consist of a solid cast mass channeled in the described manner.

Having now particularly described and ascertained the nature of inysaid invention and in what manner the same is to be performed, I declare that what I claim isl. A door or ceiling containing a series of internal iiues, in combination with a lilue for supplying a heating or cooling agent and an exhaust-line, said series of fines so connected oseille with one another and with thc supply and exhaust lines as to cause the heating or cooling agent to iow through all the flues of the series before it reaches the exhaust-tine, for the purposes set forth.

2. A iioor or ceiling containing a series of internal iiues, in combination with a iiue for supplying a heating or cooling agent thereto, means for distributing such agent to one set of the series of lues, an exhaust-line in co1n`- in unication with another set of said flues, the series of ilues so connected with one another as to cause the heating or cooling agent to circulate through all of them before it reaches the exhaust-fine, for the purpose set forth.

3. A floor or ceiling containing a series of iiues divided into groups or sets by a partition or partitions, in combination with a flue for supplying a heating or cooling agent, and an exhaust-flue, the ilucs of a group so connected with one another and the groups of fines so connected with the supply and exhaust fines as to cause theheating or cooling agent to flow through the entire series of iiues from group to group before said agent reaches the exhaust-fine, for the purpose set forth.

4. In a building the floors or ceilings of which contain series of fines, in colnbination with a vertical flue for supplying a heating or cooling agent and a similar exhaust-flue, both in communication with the series of flues in the superposed floors or ceilings, said supply and exhaust filles and said floor or ceil ing Iiues so connected and arranged as to cause the heating or cooling agent to circulate through the series of lues in the several floors or ceilings before being exhausted into the atmosphere, for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
